About 2 years ago I had a deer tick embedded in my neck for several days before I realized what was causing my pain. Finally had doctor remove it. I was tested for lyme and other related diseases. all were negative. I have had rashes including mottled skin, itchy scalp, loss of one eyebrow (suddenly) some memory problemsand more. I am 86 years old so I know some symptoms may be age related. However, I am not stupid and I know something is not quite right. Any thoughts?
